Description
Technical field
The present invention relates to a kind of combine and in combine, especially relate to the distribution in the conveyor mat of combine of the cereal that needs to be cleaned again after threshing.
Background technology
DE69709534T2 discloses a kind of combine, its threshing section and one with a roll form be arranged on threshing section below before send base plate, this threshing section has along the axle of the portrait orientation of combine, send base plate to collect the grain of taking off from cereal before this.The portrait orientation of cylinder has following consequence: before dropping on, send grain on base plate left side and right side edge region more than the grain that send base plate central authorities before dropping on.Its reason is, due to the rotation of cylinder, on cereal, produce on the one hand centrifugal force, it is not vertically to fall conventionally that this centrifugal force causes cereal behind the hole by threshing basket, but there is the lateral velocity component away from cylinder axis, threshing basket surrounds cylinder at the lower zone of roll circumference, on the other hand because cylinder has curvature, by front sending above base plate central authorities and the cereal in the threshing basket wall region of basic horizontal is compared, the cereal in the bends region by threshing basket is gathered on less area with those.
If the inhomogeneous cereal of such cross direction profiles is transported to the stage of cleaning, may occur following situation: the stage of cleaning is again underutilized on the height that front send base plate central authorities, but it is excessive on the height that front send bottom edge, to load.Consequently clean weak effect or grain loss is high.In order to address this problem, in above-mentioned document, advise: the fringe region that front send base plate is designed to tilt towards central authorities, thereby cereal tends to shift to central authorities from fringe region front sending during carrying on base plate.Yet, if when combine moves on the ground of lateral inclination, this measure is invalid.On the one hand, before can not preventing from during in obliquity at combine dropping to, this known structure send the side direction vortex of the cereal on base plate, on the other hand, just in time in a side that is loaded more consumingly cereal due to obliquity, before send the inclination of base plate ineffective, because the orientation of this fringe region is close to level, consequently, the cereal dropping on this fringe region no longer turns to central authorities, is on the contrary before dropping on, to send the cereal on the middle section of base plate to tend to shift to this side that is anyway strongly loaded cereal.
The characteristic of cereal self is also sent the distribution important on base plate front to cereal.Cereal carries out threshing on the whole circumference of cylinder, but the material after threshing can only leave threshing section along the latter half towards threshing basket of cylinder.If cereal is threshing that be dried and easy,, when material is carried and arrives threshing basket around the first half of threshing cylinder, most of material is directly by threshing basket, and the distribution of cereal in conveyor mat is offset strongly to a side.The fast rotational of threshing cylinder has promoted the uneven distribution of opposite side.
Summary of the invention
The object of this invention is to provide a kind of combine, its cereal that also can guarantee to make to need to offer with simple measure cleaning plant under changeable service condition distributes equably.
This object realizes in the following way: have one be arranged on before cleaning plant, the average throughput direction in conveyor mat is laterally separated from each other the combine of the surface texture of ground deflection with respect to cereal for the conveyor mat and of cereal, to make grain stream, provided upstream at this surface texture is equipped with the device that causes pack, and these devices make to be directed into the grain stream pack that causes on the surface texture that is separated from each other ground deflection to causing on the sub-fraction width of surface texture that is separated from each other ground deflection.The all uneven distributions that make to fall the cereal in upstream zone by pack and the order that is separated from each other ground deflection disappear and the distribution producing when being separated from each other ground deflection are no longer included to any impact.Average throughput direction generally can be understood as the direction of (being averaged on the cross section of grain stream) average pulse of each fraction grain stream.If the distribution of this stream is mirror image symmetry, average throughput direction is always arranged in symmetrical plane.
According to the first design of the present invention, cause that the device of pack is arranged in the upstream zone for cereal throughput direction of conveyor mat itself, and described in cause be separated from each other ground deflection structure be arranged on the downstream section of conveyor mat.
For by upstream zone by grain stream pack to the width of suitable definition, some ribs of restraining can be set as the surface texture that causes pack on throughput direction.
In addition the surface texture that, causes pack can comprise two central authorities towards conveyor mat of upstream zone and the surf zone tilting at average throughput direction.
Alternatively or addedly, the surface texture that causes pack comprises the first surface region that two central authorities towards conveyor mat of upstream zone tilt.These first surface regions can tilt at throughput direction, to be conducive to the motion of cereal in conveyor mat; But suitable surface configuration, the climbing that especially also can realize cereal with respect to average throughput direction in horizontal glazing bar are carried.
The surface texture that causes broadening can consist of away from conveyor mat central authorities and in the first surface region that on average throughput direction tilts two of downstream section.
According to the second design, the device that causes pack comprises with respect to average throughput direction directed worm screw laterally.
In order to expend pack cereal rapidly and with few driving power, worm screw preferably has two sections respectively with reverse thread.These two sections gather together from two contrary directions cereal respectively towards central authorities.Therefore, the grain stream that each section will be carried is less than half of all grain stream, and cereal must be short through the distance of its conveying.
Worm screw preferred parallel is in a rotor orientation, and this rotor is separated (conventionally distributing on the rotor axial) material being gathered together by worm screw from grain stream.
Describedly cause that the surface texture that is separated from each other ground deflection preferably includes two second surface regions that tilt away from conveyor mat middle ground.From causing that the grain stream part that the surface texture of pack arrives second surface region is transferred far in conveyor mat, they are just separated from each other widelyr.In order to be conducive to carry, these second surface regions can as above be set forth about first surface region tilts and/or glazing bar is set like that.
In order to make better the effect in these second surface regions and the obliquity of combine irrelevant, these second surface regions are transversely tilting at combine more consumingly than two first surface regions (if any) of upstream zone preferably.Even if combine moves on smooth ground, second surface region strong tilt is in the horizontal also favourable, to realize the strong broadening of grain stream on short transport path.
These two second surface regions can be surrounded by the 3rd surf zone in both sides, and these the 3rd surf zones tilt and also may tilt at throughput direction towards the central authorities of conveyor mat.When the downstream section of conveyor mat also meets with the cereal falling, it is especially favourable that described cereal turns to central authorities by the 3rd surf zone.
Downstream edge place in conveyor mat can arrange at least one projection, and this projection is on the marginal prolongation between two surf zones that tilt toward each other.Being raised be like this beneficial to make may be too intensive on marginal height grain stream again loose.
Describedly cause that the surface texture that is separated from each other ground deflection can be divided into a plurality of substructures for tributary, the first substructure in these substructures is divided into many tributaries and each further substructure by the stream of pack the tributary that is fed to it is cut apart again.Therefore can in short distance, obtain many tributaries that distribute on the width of conveyor mat.Even if the width in every the independent tributary obtaining is like this little, if the quantity in these tributaries is abundant, also can obtain cereal being uniformly distributed on the width of cleaning plant.
According to a kind of preferred design, three such substructures can be different, wherein, the first substructure forms by two inner surface area of downstream section, and the downstream edge place of other two substructures by conveyor mat convexes to form, these projections are separately positioned on the marginal prolongation between the surf zone that tilts toward each other.It is excessively intensive on this marginal height that these projections can be resisted grain stream.
Above-mentioned conveyor mat can be particularly advantageously unique with one, separation rotor directed on longitudinal direction of car is combined with, because this conveyor mat compensates the cereal uneven distribution relevant to this structure effectively.But this conveyor mat is also suitable as the pretreatment base plate on threshing basket, especially when threshing unit is configured to axial threshing unit.

Embodiment
In Fig. 1, to be loaded with adjustable for height reaping apparatus 3 according to combine 1 of the present invention in its front region shown in profile, this reaping apparatus 3 gathers in ripe cereal 9 and in side direction, cereal is pooled together and offer incline conveyer structure 10 on large width.Cereal arrives separating mechanism 4 by inclined belt type conveying plant 10 in known manner, and in the view of Fig. 1, this separating mechanism 4 comprises that a threshing cylinder 11, is arranged on threshing cylinder 11 bending roller 17 and a threshing basket 12 below.Main the first grain stream being comprised of grain, crushing straw and husk is separated and is fallen on pretreatment base plate 13 through the hole of threshing basket 12 from cereal.Grain stream on pretreatment base plate 13 is carried towards the direction of cleaning plant 5 backward by the balleting of pretreatment base plate 13.Pretreatment base plate 13 is provided with horizontal glazing bar from the teeth outwards, to grain transportation rheology on ascent direction is obtained easily.
Fail by bending roller 17, to be further transported to axial rotor 18 through this part grain stream of threshing basket 12, this axial rotor 18 combine 1 longitudinally on extend past the major part of combine length.Axial rotor 18 thereunder region is surrounded by semi-cylindrical sieve 20, and the second grain stream being mainly comprised of grain and fringe section is separated and fallen on loopback base plate 22 via this sieve 20.
Also can be arranged side by side two parallel axial rollers and replace an independent axial roller 25.
What at axial rearward end 25 places of roller 18, dish out is mainly that the cereal of stalk arrives at the distribution apparatus 8 that is positioned at combine 1 afterbody, and this cereal is shredded and finally scatters in ground by stalk smashing apparatus 28 at this.
The second grain stream is transported forward and is fallen on pretreatment base plate 13 finally by the leading edge of crossing loopback base plate 22 on the loopback base plate 22 of balleting, and this second grain stream is combined together in this and the grain stream occurring through threshing basket 12.
The grain stream being combined together is transported to cleaning plant 5 by pretreatment base plate 13, and this cleaning plant 5 comprises top sieve 15, lower sieve 16 and fan blower 14, and this fan blower 14 orders about air stream and scraped from sieving 15,16.Be included in from the grain in the grain stream of pretreatment base plate 13 and by these two sieves 15,16 and by the base plate 19 being positioned under these sieves, arrive screw feeder device 23 and lift 24 successively, lift 24 is transported to grain to be arranged in driver's cabin 7 tanker 6 below.
The sieve 16 or drop in the process of base plate 19 from lower sieve 16 dropping to top sieve 15 from pretreatment base plate 13, from top sieve 15 drops to, composition lighter than grain in grain stream is caught and is taken away thereupon by the air stream of fan blower 14, arrives distribution apparatus 8 and separates by this distribution apparatus.Heavy, more clumsy composition by residue on sieve (
) at sieve 15,16 rearward end places, arrive in a ditch laterally extending below sieve.A worm screw of rotating in ditch 21 is laterally shifted to the second lift 27 by this material, and this second lift 27 is transmitted back to separating mechanism 4 by this material.
The efficiency that light part is separated from grain in dropping process is relevant with the density of grain stream, and the in the situation that of given flow, grain stream distributes more evenly on the width of the sieve 15,16 of pretreatment base plate 13 or cleaning plant 5, and described efficiency is higher.In the upstream region of loopback base plate 22, grain stream is not equally distributed on the width of this base plate, but in the lateral edge of loopback base plate 22, below the bends region of the outer surface of the sieve 20 of axial rotor 18 than more intensive at the middle part of loopback base plate 22, the sieve 20 that is positioned at this top, middle part is at most slight inclination at this.In addition,, due to the rotation of axial rotor 18 and the threshing situation of cereal, cause the cereal left and right skewness falling.
Fig. 2 illustrates a part for the interior arrangement of combine 1 with stereogram, i.e. axial rotor 18 and around sieve 20, loopback base plate 22, the pretreatment base plate 13 with glazing bar, the fan blower 14 that is placed in pretreatment base plate 13 belows and the top sieve 15 of this axial rotor 18.
The surface of loopback base plate 22 is structured, to make be evenly distributed of cereal on width in the process of grain transportation in conveyor mat 22.By Fig. 3, set forth the first embodiment of this structure, Fig. 3 illustrates separately the loopback base plate 22 of Fig. 2 with the stereogram leaning forward.The section 33 below in view upstream, at Fig. 3 of loopback base plate 22 comprise two substantially smooth, forward and the surf zone 34,35 tilting a little toward each other, these two surf zones are sentenced obtuse angle at turning line 36 and are joined each other.Turning line 36 extends below the axis of rotor 18, shape due to rotor 18, near the cereal dropping on loopback base plate 22 edges is more intensive than dropping on turning line 36 cereal around, these drop near cereal edge under the ordering about of the balleting of loopback base plate 22 towards turning line 36 and downstream section in other words the place ahead section 37 move.
On surf zone 34,35, along roughly in altitudinal gradient direction directed rib 38 by grain stream pack to loopback base plate 22 width about 1/4th to 1/3rd on.The surf zone 39,40 that so stream of pack is encountered forward and tilted away from each other in downstream section 37, described stream separates and makes every effort to be separated from each other to the left and right on these surf zones.Surf zone 39,40 intersects each other on the straight line prolongation of turning line 36.The lateral tilt of surf zone 39,40 is greater than the lateral tilt of surf zone 34,35, to extend longitudinally the strong separation that also can reach these tributaries very little in the situation that along combine 1 at downstream section 37.
Cereal in the part that is positioned at rib 38 downstreams that the surf zone 41,42 being connected with right side with surf zone 39,40 left sides, tilt forward and toward each other makes to drop on the cereal on surf zone 41,42 or drop on surf zone 34,35 is to middle part deflection.
The length of surf zone 39 to 42 and drop are preferably so mutually adaptive, make to realize being uniformly distributed on the whole width of grain at loopback base plate 22 at leading edge 43 places of loopback base plate 22.
If desired, by an outstanding projection 45 that surpasses the top formula at edge 43 is set respectively on the prolongation at turning line 44, can prevent that grain stream is too intensive on the height of the turning line 44 between 40,42 in other words at the surf zone 39,41 adjoining each other.
Might not require grain stream in upstream zone 33 a unique position pack, but also can in section 33, produce two parallel tributaries and in downstream section 37 by these two tributaries broadening again, as long as can structurally guarantee that the flow in these two tributaries and the width of lead edge portion are proportional, fall on pretreatment base plate 13 through this lead edge portion in these tributaries.The loopback base plate 22 of take in Fig. 4 is example.In this loopback base plate 22, those surface textures of describing with reference to Fig. 3 by double structure respectively respectively on the right and the left side of turning line 46.Turning line 46 longitudinally extends a little obliquely with respect to combine, to obtain the stream of same intensity in turning line 46 both sides in the situation that consider to fall the side direction vortex that the rotation by axial rotor of the grain on loopback base plate produces, to be distributed in respectively mode on half leading edge 43, to drop on pretreatment base plate 13(not shown in Fig. 4 subsequently for these streams) on.
Fig. 5 is partly with vertical view, partly illustrate according to the combine of the present invention's the 3rd design with very schematic horizontal cross.One incline conveyer structure 10 heart from reaping apparatus 3 departs from extends to threshing-separation rotor 52 on driver's cabin 7 right sides, and this threshing-separation rotor 52 has at the transversely directed rotation of combine and is positioned in driver's cabin 7 below and partly below driver's cabin 7.Cereal by incline conveyer structure 10, at the right part place of threshing-separation rotor 52, be fed into threshing-separation rotor 52 and by threshing-separation rotor 52 until be positioned at the outlet at place, left part.Threshing-separation rotor 52 has merged the threshing cylinder of combine and the function of axial rotor 18 of Fig. 1.One grain stream by surround threshing-separation rotor 52 basket hole with the mode that distributes on longitudinally at this basket out and this grain stream mainly by grain, crushing straw and fringe section, formed, this grain stream arrives passing away 53, one worm screws 54 that extend in parallel with threshing-separation rotor 52 and rotates in these passing away 53 bottoms.
The composition of material stream is not out constant in the length of threshing-separation rotor 52.Along with the carrying out of threshing course, the ratio of non-grain composition increases progressively from right to left in Fig. 5.Worm screw 54 comprises two sections 55,56 respectively with opposite threads rotation direction, and from threshing-separation rotor 52 material out, by the rotation of this worm screw, the central authorities towards combine are pulled to together.The outlet 57 of passage 53 is on the height of the turning line between these two sections 55,56.
Due to the stirring action of worm screw 54, on it forms, material is flowed through by outlet 57 arrival pretreatment base plates 58 uniformly, the same with the loopback base plate in the design of seeing before, this pretreatment base plate 58 has some surf zones 59 to 62 different, that tilt relative to one another.Outlet 57 two of leading in these surf zones, 59,60, these two surf zones as shown in the arrow by marking towards both sides and recede, to the material stream coming down in torrents is thereon divided into two tributaries towards both sides broadening or by this material stream.In both sides, surround region 59,60 and as equally by as shown in the arrow marking towards vehicle central and sweptback surf zone 61,62 define these two tributaries split movement border and these two tributaries are deflected on several plates 63 crossing to the top formula of joining, these tributaries are at these plate 63 places again branch.Therefore obtain four tributaries that intensity is identical, of pouring to respectively four parallel bands 65 of pretreatment base plate 58 from these plates 63 in these tributaries is upper, and these bands 65 are spaced from each other by three vertical outstanding ribs 64.
The inclination of having illustrated surf zone 59 to 62 and pretreatment base plate 58 in Fig. 6, Fig. 6 shows combine along the partial sectional view of the plane representing with VI-VI in Fig. 5.Can identify outlet on passage 53 walls 57 and be positioned at a section of this outlet 57 worm screw 52 below.The cross section of surf zone 59 to 62 formation W shapes and tilting towards observer to the band 65 of pretreatment base plate 58 is the same.
The sieve by cleaning plant 5 and arrive one at the material that the rear edge of these sieves falls and be arranged on residue on sieve conveying worm 66 below these sieves and get back to passage 53 by this residue on sieve conveying worm 66 and the residue on sieve lift 67 that joins with it not.
The grain by these sieves arrive grain conveying worms 68 that are arranged on these sieve belows and by a unshowned grain lift arrive one unshowned in the drawings, be arranged in the tanker above pretreatment base plate 58.
